Perhaps he didn’t get the memo, but a RIM employee has given a video demo of a new BlackBerry 10 L-Series device ahead of launch.

The video appears to have been shot at a trade show in Mexico, with the employee giving a full demonstration of the unnamed touchscreen device’s camera, app store and virtual keyboard.

Thanks to the overzealous hands-on briefing, we get to see BlackBerry 10’s perfect photo feature, that enables the user to go back and forth in time by a mere millisecond, ensuring your photo is not ruined by a blink or sneeze. We also see how letters can be “flicked” on to the screen from the virtual keyboard.

It’s unclear what the name of the device is – we’d welcome any Spanish translations – but speculation is that RIM’s first L-Series phone (the name given to all of RIM’s touchscreen BlackBerry 10 devices) will be London. Perhaps this is our first “official” glimpse at the BlackBerry London in action.
